SPEGIFIGATION forming part of vLetters Patent N o. 707,590, dated. August 26, 1902. Application filed January 2, 1902. Serial No. 88,105. (No model.)

To @ZZ whom, it may concern.:

Be it known that I, DANIEL M. HOLMES, a citizen of the United States, and a resident of Arlington, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Double-Stroke Deposi` tors, of which the following is a specification.

My invention relates especially to means and mechanism employed fordepositing se miro iiuid confectionery material in molds, rbc.,

and has for its object the provision of a simple and effective depositor whereby a plurality of layers of material may be deposited, the number being regulated at will.

To attain the desired end, my invention consists in the combination, with a material hopper or holder provided with exit-orifices, of a discharging device in which is comprised two independently partially-rotatable oscilla- 2o tory members located in a common throat, one of said members being provided with ports or orifices; and my invention also involves certain novel and useful combinations or arrangements of parts and peculiarities of conz5 struction and operation, all of which will be hereinafter first fully described and then pointed out in the claims.

In the accompanying drawings, forming a part hereof, Figure 1 is an end elevation of a 3o depositor embodying my invention. Fig. 2

is a side elevation thereof. Fig. 3 is an enlarged vertical sectional view at line x no of Fig. l. Fig. i is a plan view looking down upon Fig. 3. Fig. 5 is a side elevation of one of the material-directing devices removed from the hopper. Fig. 6 is a top plan view, and Fig. 7 a bottom plan view, of the same.

Similar numerals of reference wherever they occur indicate corresponding parts in all the 4o figures. 4

l is the main frame of the machine.

2 is the bed.

3 is the belt for carrying the mold-trays.

L is a material hopper or holder mounted above the main frame and having at its bottom semicircular seats or throats 5.

(5 is a central division or partition provided with offsets 7 and S, projecting into the throats 5.

9 and 10 are discharge-ports. 5o

11 represents shafts journaled at the ends ofthehopperandbearingtonguesl2. Upon one end of each shaft 1l is a pinion 13, arranged to engage with a rack 14, which may be caused to reciprocate by any suitable Surrounding the shaft 11 is a hollow shaft l5, provided with broken rings 16, eX- tending between the tongues 12, the peripheries of the rings 1G corresponding tothe contour of the seats 5. Projecting from the hol- 6o low shaft is a longitudinal tongue 17, having perforations 18 therethrough opposite to each tongue 12 upon the shaft 11. rlhe hollow shaft 15 passes through the sides of the hopper t and bears a pinion 19, which engages with a reciprocable rack 20.

Referring to Fig. 2 of the drawings, it `will be seen that the rack 2O engages with a rockarm 21, bywhich it may be reciprocated. In

order to provide means for disengagiug the 7o rock-arm from the rack when it is desired to vary the number of discharges of material bottom of the hopper are comprised of a shell I' 26, screwed or otherwise held in place in the 8o body of the hopper. This shell26 has at one side an opening 27, corresponding to a discharge-port 9. Within the shell 26, below the top, is an inWardly-projectingiiange whereon is supported the flange projecting from a central discharge tube 28, the opening therethrough registering with a discharge-port 10.

32 is a thimble held in place upon the tubev 2S by means of a screw or pin 29 and having discharge openings 30 through its bottom 9o portion.

3l represents teeth formed upon the periphery of the thimble 32. The parts 26,28, and 32 form the walls of an annular cham ber with which a port 9 communicates.

33 is a pin which projects upward from the base of the thimble 32 within the annular chamber.

34 is a rack which engages with the .teeth 31 upon the thimble, and 36'is a crank whereby said rack may be reciprocated.

The operation of my depositor is as follows: Material being supplied to'the hopper upon each side of the partition therein, in starting the moving parts the tongues 12 and 17 of the f oscillatory members of the discharging mechansm rest against each other, such position of the tongue l2 being indicated by the dotted line in the right-hand portion of Fig. 3 of the drawings. These two members move together until the tongue 17 covers the port 10, when the movement of such tongue ceases. The tongue 12 continues to move in the same direction, drawing material from the mass within the hopper through the perforation 18 in the tongue 17, filling the space between said tongue and the tongue 12. Before the tongue 12 passes from its seat in the throat of the hopperl its movement is stopped in accordance with the quantity of material it is desired to deposit. The tongues 12 and 17, with the material held `between them, now move in the opposite direction until the tongue 17 strikes the offset 8, closing the opening through the tongue and opening the port 10. The continued movement of the tongue 12 forces the material in front of it through the port 10 and the tube 28 to the mold. The discharging mechanism upon the opposite side of the partition now operates in the same manner as above described, forcing the material into the annularchamber in the directing device, the rack 34 imparting a rotary movement to the thimble 32, present-ing all parts of the chamber to the supply-port, and at the same time the pin 33, moving with the thimble, passes through the material in said chamber, keeping the material homogeneous and insuring an even flow. The material passes from the annular chamber through the perforations 30 in the'base of the thimble.

By varying the number of oscillations of the discharging devices through the medium of the changeable motion of the reciprocating racks one kind of material may be completely inclosed Within the other or dii-ferent materials may be deposited in a plurality of layers.

Having now fully described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

1. The combination with a material hopper or holder provided with exit orifices or ports, of a discharging device in which is comprised two independently, partially-rotatable, oscillatory members located in a common throat, one4 of said members being provided with ports or orifices.

2. The combination with a material hopper or holder provided with exit orifices or ports and a division or partition, of discharging devices in Aeach of which is comprised two independently,partially-rotatable,oscillatory members, located in a common throat one of said members having openings or ports therethrough.

3. In a depositor, a discharging device in which is comprised two independently, partially-rotatable members,located in a common throat, as set forth, one of said members being perforated and arranged to come in contact with a projection extending into the throat.

4. In a depositor, the combination with a discharging device in which is comprised two independently,partially-rotatable,oscillatory members, located in a common throat, of means for varyin g the oscillation of said members.

5. In a depositor, the combination with a material hopper or hold-er provided with exit orifices or ports and discharging devices at the bottom of the hopper, of directing devices in each of which is comprised a central exit-tube having communication with one side of the material-hopper, and a chamber surrounding said exit-tube having communication with the other side of the materialhopper, discharge-openings leading from said chamber, and means for rotating the bottom and inner wall of the chamber.

6. The combination with a fixed shell at the bottom of the material-hopper, of a central discharge-tube and a thimble rotatably held thereon; a supply-port at the top of the thimble and discharge-openings at the bottom of the thimble, and means' for rotating the thimble.

7. The combination with a fixed shell at the bottom of the material-hopper, of a ceutral discharge -tube and thimble rotatably heldv thereon, the thimble having a supplyport at the top and discharge-openings at the bottom, a pin located within the thimble, and means for rotating the thimble.
